LED Notification flash - Not working?

I haven't fully tested this issue yet mainly because I've only had the phone for a few days... I wanted to check if anyone else had this problem.
Under Settings -> Sound & Display -> Notification Flash
I have all the options ticked.
In theory, whenever I have a missed call or a SMS or email etc, I should be able to tell that I need to check my phone be a little blinking light in the top right corner off the screen. I just came back to my phone and this LED wasn't blinking but when I turned on the phone, there was a missed call and a SMS.
Other times, it seemed to work fine.
Anyone else noticed this problem?

it only flashes for 5 mins and then stops. There is no way to change this without additional apps.

Oh... How disappointing. Pretty useless imo. Thanks for the info. I wonder if they will fix it. My previous phone, Touch Diamond, had something similar but it never stopped flashing until you looked at your missed calls.

Now that explains things. I tend to look for the led after I've not used the phone for a while. In my pocket or elsewhere. Quite a few times I've seen no flashing but have a notification in the top left. I thought it was another one of those little 'features' we keep finding.

Yeh i discovered this awhile back and it's annoying as hell, i just use a app called Missed Reminder which can be configured to allowed it to keep flashing indefinitely

I was just going to make a post about this. I thought the LED notification wasn't working at all on my Desire, since I've never seen it, but perhaps it had just stopped before I had the chance to catch it, then

What apps are you referring to? It would be nice to be able to have the LED flash longer.

I'm guessing this is to save battery time, I don't know how much power a small LED uses but it surely can't help with the already abysmal battery life

I first thought the LED was located behind the optical trackpad, because the trackball on my Hero could light up. I think the LED-notification is pretty dumb since it's almost invisible when it lights up. The lighting trackball was much much better

This is a known issue. I thought that did not happen in Android, but I guess I was wrong.
If the phone work in Windows Mobile, there are a registry key to let assign values to the options, so they are usable.

In Android, I have no clue... maybe my info help in any way.
PMoto

It would be nice to be able to change the flash time from the default 5 minutes, or atleast an option for no time limit.
I know it's to help save battery life, but I'm willing to say that the light flashing will use less battery then the back light coming on everytime I'm away from my phone for more then 5 minutes, from me checking to see if I have new messages, email, or missed phone calls.

Same issue with my recently purchased A40.
No blinking at all despite screen flash notification selected.
Hope someone can help

Notification LED doesn't flash

The new message notification LED on my (new) LTE Gnex only flashes once or twice, just when the phone boots up. Doesn't flash when a new message arrives. I've tried disabling it, and re-enabling it in settings, but it just does not work. This does not seem normal, and I'm wondering if I need to return the phone, which I really don't want to do. I've already unlocked the bootloader and rooted, but still running the stock ROM.

Have you tried Light Flow from the Market?
This has worked with the stock ROM.
I personally use Trackball Alert Pro - MoDaCo ROM has suppport for this.

Just tried calling myself, and hung up. The LED isn't lighting up. But I have seen it blink for emails at least. Hmm.. maybe try light flow.

Have not tried any 3rd party apps, yet. First I wanted to know if there was a problem with my phone, or if this is "just" a bug. If others have this same problem, then I'll try a 3rd party solution. Thanks for the feedback.

Tried the same thing, called myself and sent messages with no led notification. Thought my led was broken but then installed light flow and it worked no problems.
Not sure how it was supposed to work stock but could not get it to work at all without a 3rd party app.
Without the app, the only option I could fight was pulse notifications which I tried turning on and rebooting but it never seemed to work.

Just tried light flow. When I tried the "test LED" function, my phone would no wake from sleep. Also got sleep of death when I got an email. Had to do a battery pull. Any solution for this?
I looked at Trackball Alert and it requires Paul's ROM, which I'm not ready to try (yet).

I noticed it doesn't light up when it's charging either. Is this normal behavior?

From what I've seen so far the stock light is a hit and miss for me. Only time will tell how they will improve this.

Do you have it set on? Lol that's all I can think of. Mine works fine

Yes, mine is enabled.

Well its not your phone....The light stock is stupid I have no idea why you would include a light that only flashes random times and only in white..... I had issues with lightflow crashing my phone when waking with several notifications flashing. Just bite the bullet an flash ARHD or Paul's rom they both support Trackball notification and it works very well!!

Yep. Probably don't have/use most apps that support it for me to notice it all the time.

I've been having the same trouble. Haven't seen the light in days.
I went back and revisited some of my settings. I had turned on the setting for the screen to "stay awake while charging." I unchecked it, and now my light is working again.
Now, it only ever comes on when the screen is off to begin with. It won't come on if the notification happens while it's already on.
But at least the light comes on when the screen is off now!
(And I really wish the blink rate was higher. You can look at it for several seconds between blinks, and think there's nothing and look away.)

So the change I made to the settings seems to have fixed the light issue. I have been properly getting notifications since I turned off the keep awake. Seems like an easy enough to fix bug as long as they know about it.
But now what I want is a faster blink rate. One second on out of every 6 or 7 seconds is easy to miss.

[APP] Light Flow

the developer has claimed the latest version on the play store is working for rooted phones, but I still am not having the best of success. I thought I'd start a thread and see how others are fairing.
The newest version has some improvement; being able to select different colors for different notifications and actually getting them to go off when you've pulled down the notification bar. however, it doesn't blink for me at all. When i get a text or email the corresponding light is a steady constant light if the screen is asleep. If you wake it up the light either disappears or only lights up very infrequently.
I've read some posts before the latest versions came out that some users had success getting it to work by actually turning Accessibility off. This seems to turn off the entire app for me.
anyone having better luck?

I have had the current version working correctly both on a stock TW rom, and now on CM10. The flashing lights haven't been implemented yet, however he is working on it.
The only thing I had to do on the Samsung TW rom was disable Samsung TTS in the manage apps settings. Once I set it to S3 root mode, everything worked perfectly.
I suggest you follow his blog here:http://www.folioflow.com/ff/page/website/lightflow/pageId/1826

I have done all that including following the developers blog. I have accessibility on, only have the light flow notifications turned on, allowed SU access to light flow app, and have tinkered around with it all weekend but it still isn't working correctly. It works fine when the screen is on, but when the screen is off it gives a solid light.

Its not supposed to blink get, that's why I linked you to his blog.

A blinking light will kill the battery or at least use more juice. Dev did say he is looking into that feature tho
Sent from my SGH-T999 using xda premium

Developer advises blinking uses more battery than solid notification. Go figure.

Since I installed Light Flow, whenever the screen is off the LED glows a faint green. First I disabled Light Flow and the led still glows green. I unchecked it under Accessibility and rebooted, still green. Just had to uninstall and reboot to get it to stop. Anyone else have this issue? Is there a setting I'm missing somewhere?

I had that issue when I restored from an old version of light flow. The newest version that I installed straight from the Play Store works fine.

I believe to get other colors other than green, you need to be rooted and go into the app settings and check "S3 root mode" or whatever its called...
Works perfect for me.
EDIT: I think the updated app (as of today) should work whether your rooted or not.

The update version today also supports blinking in adjustable intervals.

You guys should just install cm10 on your phones, it already comes with notification light settings & it works perfectly :good:

I would agree with that almost fully except it's a pain setting up different notification sounds between e-mail and sms/mms. It's also nice to be able to have it make notifications at intervals from missed calls/sms and the light to go away eventually if you want.
But I do have to say, I'm on CM10 - Paranoid Android ROM(latest build) and light flow is working like a charm for me right now. Looks like the bugs have been worked out for the most part.

Hi guys.. I have an international S3 and since a recent Lightflow update, I regularly get lightflow causing wakelock for hours. even with no outstanding notifications. I've uninstalled, re-installed - same problem.
Happened 3 times this week. reboot fixes it.

[Q] Just purchased, notification light not working and other questions

Hello. I purchased the Epic 4G Touch two days ago from Best Buy, and I've realised that the notification light doesn't work correctly. When it's plugged in and charging it glows red, and when it's done charging it glows blue. But when it's not plugged in and I get an email, text, missed call, voicemail or Gmail notification, the light doesn't light up. I've checked that SETTINGS > DISPLAY > PULSE NOTIFICATION LIGHT is ticked, and it was. I've unticked it, shutdown, R+R battery, rebooted and re-ticked it, and still I have no light notifications.
I haven't rooted the phone, it's basically as it was out of the box, on Android 4.0.4, FH13, using the stock messaging app, stock email app for AOL mails, and the Gmail app. I can't see in any of those apps that I have to turn on LED notification, so I don't know what I'm not doing correctly.
Second question is that the guy at Best Buy told me that I should install the Battery Charged Silencer app from play.google.com/store/apps/ details?id=cz.psencik.simple.silence so that my phone doesn't beep in the night when it's done charging, Well, that's all well and good, but my phone doesn't beep when it's done charging, and actually, I'd like it to -- at least during the day -- so how do I make it so that it does beep when fully charged?
Third, I've noticed that the phone's brightness changes occasionally, but only when I open the browser. It's isn't because of Auto brightness, because it happens when I'm stationary in a room where the lighting level hasn't changed (and I don't use Auto brightness anyways). I usually set my phone to be pretty dim, but the browser is often much brighter than that when I open it. When I'm lying in bed, especially, I don't want to get blinded or disturb "Mrs me" when I access the internet. Does the browser have it's own brightness setting? If so I can't find it, so how do I set the browser brightness to be the same as the rest of the phone's? Or do I just have a dodgy screen light?
Also regarding the stock browser, coming from an Android 2.2 handset I fully expected things to be different, but I can't get the browser to open my bookmarks or give me access to the address bar unless I scroll back up to the top of the page. Am I missing something really obvious here, or is that just how it is now? It used to be that pressing the Menu button would let me do that, but it doesn't seem to work that way any more, and it's really annoying to have to scroll to the top of a very long page when I want to go to open a new page.
Fourthly, I know that the pre-installed apps can be deleted, and might have to do it with TelenavGPS. I clicked the app, which popped up with a notification that said "An update is required". I tapped the "update now" button, which opened the browser which opened Play Store, but the Play Store says the app is up to date. Should I delete it and re-download from the Store, or just delete it and stick with the Google Maps/Google Navigation apps? Why does Sprint install this when Google's comes installed as well? Is it supposed to be better?
And the last thing I'm confused about at this point is when I'm in the app drawer and tap the Menu Button and then Edit. When I tap the minus sign next to an app, it pops up with "This application will be deleted" and a Yes and a No button, but it isn't clear (to me) whether it will get deleted from my phone or just deleted from the app drawer.
Thanks for any help or info anyone can give me about these things. I know they don't seem like major problems, but they niggle at me and I can't help but worry that I picked the wrong phone or have a faulty one (with regards to the bad notification light and random dimming and brightening at least) that I need to exchange while I'm in my return period.

Browser has its own brightness settings. Hit menu and scroll down. Its right there.
Yes the address bar will scroll out of the screen when you scroll down.
No idea about the beep. Notification led should work. May be some one stock can check on that.
Remove telenav. Use google maps.

LED used to work on gingerbread for me but never on ICS TOUCHWIZ, works on AOSP though. Since I'm in a touchwiz ROM I'm just using blink app to make it work.

I use the app light flow for my notifications and make it blink blue. The app blink also works.
Not sure about telenav, never had any issues. You have to be rooted to remove some stock apps like the Sprint and Samsung stuff and I highly recommend it.

Notification LED was broken in FF18 and FH13 OTA releases. It is now fixed in FI27 which will be available OTA soon, also available via Kies.

Touchwiz is the Samsung launcher/ui just like HTCs sense and motos blur. My phone has never beeped when it was charged, and download and install kies on your PC and see if fi27 is available. Or check the fi27 discussion thread in general sub forum

Notification LED simulation App

I stumbled on Reddit at this cool App that simulates a Notification LED using the actual screen. It was also featured on XDA and I decided to give it a try on the Mi9T. The App is called NotifyBuddy and is available for free on the Play Store.
My experience with it over a whole day was great. It actually looks like an LED lighting up. Since we have a Amoled screen it just uses a tiny part of the screen, so there is no huge battery drain. Also to prevent burn in it moves slightly in position every 5 to 10 minutes or so from left to right. You can have different colors for different Apps and how long the LED effect will be active until switching off. I have mine on for 5 minutes.
My major concern was battery life since when the App is active the phone probably doesn't go to deep sleep but after now 24 hours of the phone being unplugged I can say it's great. Just look at the Screenshots. I'm at 50% right now and almost 4,5 hours of SOT over 24 hours of usage. It works very well so far and if this doesn't get worse there is no reason to not keep it. Try it out guys if you are missing a Notification LED on the actual front of the phone.

Doesn't work for me, do you use your fingerprint scanner to unlock because I suspect it might be conflicting with that. None of those similar apps ever work for me

Doesn't work for me also, there its no way to make it work

Weird. It works for me

Doesn't work for me. I use fingerprint scanner. Wish it did work though, as this would be really helpful.

I guess you granted the app the required permissions ( asked when you first launch it) and allow notifybuddy to start in backgroup, display on lock screen ?

I advise you to try this:
1. Remove the fingerprint.
2. Run the application, when you first start, allow notifybuddy to run in the backgroup, display locks on the screen.
3. And then create a fingerprint.
4. Reboot the phone.

A
- I received the 10.3.10 by OTA... (you can manualy check for update into the "about phone" section)
- NotifyBuddy is working with Fingerprint unlock activated. The fingerprints where created before installing the app.

Tried deleting fingerprint before installing the app.
Then tried again after.
Could not make it work. If anyone has any more suggestions, they will be very much appreciated.

Prof Reminder. Use this app and forget about any other app that involves notification LED. I use this app since i received this Mi9T. I was upset for missing the usual notification Led and i have searched for other options. This app does not consume any battery and is very easy to set up. When you have missed notification (WhatsApp, sms, call, etc), this app reminds you over and over.... Sorry if it's off topic or something but i just try to help! Respect!

Dude, you "saved my life"with this application.
I came from a OnePlus 3 and never had a Xiaomi phone before, and the lack of a visible LED was annoying me a lot.

I had it work for all of 5 mins and no matter what I try I cant get it to work.
